Vibrant and rich fluoro-colors The Sea Dragon Fluoro-Dual Beams Royal blue LEDs emit blue light in the range of 450-460nm that is in the approximate wavelength to excite the fish, plants or organisms into making a light filled energy response; SeaLife adds a finely tuned and proprietary dichroic filter that pinpoints the exact light wavelength so to get the highest energy response from the underwater subject results.

Enhance your underwater fluoro-viewingTwo universal, barrier filters are included to improve your experience in underwater fluorescent viewing and imaging. The mask filter fits over the dive mask to filter out the residual presence of blue light emitted by the light (its the response from the sea creature you want to see, not the blue light). The second filter attaches to any underwater camera with a lens diameter up to 47mm.

Easily expand with Flex-ConnectA Flex-Connect Single Tray, Grip and fitted case are included with the light. Flex-Connect allows you to quickly and easily transform your camera set from compact to full-featured in just seconds by adding grips, Flex Arms, trays and more with just a "click!"

For BEST results and SAFETY reasons, the Sea Dragon Fluoro-Dual Beam uses Cree Royal Blue LED's combined with a proprietary dichroic filter. SeaLife NEVER has and never will use Ultraviolet (UV) LED's.

Some companies are selling underwater UV lights claiming the results are better than blue LED's, and that there is no need for yellow barrier filter over your mask and/or camera. The truth is that UV lights pose a serious safety hazard to the eyes of humans and sea creatures. UV light is invisible, so you don't realize that your eye is being bombarded with UV rays. It is a proven fact that extended exposure to UV light has been linked to eye damage, including cataracts, macular degeneration, pingueculae, pterygia and photokeratitis that can cause temporary vision loss.

The Sea Dragon Fluoro-Dual beam's Blue LED's, combined with our exclusive dichroic filter, emits a powerful blue light creating the optimal wavelength to excite underwater organisms. To see the fluorescence effect best, two yellow barrier filters are included - one for your mask and another for your camera. The primary purpose of the yellow filters are to absorb the visible excess blue light, so you only see is the fluorescence effect.

Underwater testing shows that more sea creatures fluoresce when exposed to the Sea Dragon Fluoro-Dual Beam when compared to UV lights.

The Fluoro-Dual beam light is a collaboration with Fire Dive Gear, a leading authority in underwater fluorescence diving. For more information about fluoro diving, specialty courses and custom-made filters, please visit www.firedivegear.com.

The beam angles for the Sea Dragon lights are shown as the true, tested in-air (above water) beam angle. Underwater, due to light refraction, the angle tightens to approximately 33% less.

Avoid using this Sea Dragon light above water for prolonged periods of timeThe light is designed for underwater use and water is needed to displace heat. The metal light head at full power will reach temperature of about 140F (60C) degrees within a few minutes, which may cause burning if touched. A thermal sensor will automatically dim the light if internal temperatures reaches 150F (65C) degrees. Immediately turn off light if any parts of the light become hot to the touch.
